Influence of Growth Rate and Magnetic Field on Microstructure and Properties of Directionally Solidified Ag-Cu Eutectic Alloy.

This materials study examined how growth rate and an external magnetic field affect microstructure and properties in directionally solidified Ag-Cu eutectic alloys. The lamellar spacing followed the Jackson-Hunt model with a reported constant of 5.8 µm³/s. Increasing magnetic field tilted eutectic growth and…

[Mechanism of action of combined extremely weak magnetic field on aqueous solution of amino acid].

The paper reviews and analyzes mechanisms for resonance action of extremely weak alternating magnetic fields (40 nT) combined with weak static fields (40 μT), tuned to cyclotron frequencies. It references prior reports of narrow resonant peaks in electrical conductivity of aqueous solutions and biomedical effects in…

Impact of a pulsed electric field on damage of plant tissues: effects of cell size and tissue electrical conductivity.

This experimental and modeling study examined pulsed electric field (PEF) permeabilization in several fruit and vegetable tissues at 293 K using 1000 μs pulses and field strengths of 400 and 1000 V·cm(-1). While electroporation theory predicts greater damage in tissues with larger cells, the authors report this…

Influence of mashed potato dielectric properties and circulating water electric conductivity on radio frequency heating at 27 MHz.

This engineering study used experiments, computer simulations, and simplified analytical calculations to examine how mashed potato dielectric properties and circulating water electrical conductivity affect RF heating at 27 MHz. The authors report that higher circulating water conductivity and higher salt content in…
